SN74AVCA406LZXYR is listed in the Translators, Level Shifters range at ChipApex. The manufacturer field lists Texas Instruments. Its product description is IC TRANSLTR BIDIRECTIONAL 20BGA. Review the specifications below when checking this part for your BOM.
The SN74AVCA406LZXYR is a voltage-translation transceiver from Texas Instruments, designed for memory card interfaces. It operates with a supply voltage range of 1.2 V to 3.6 V and features a propagation delay of 5.4 ns. The device supports an operating temperature range from -40°C to +85°C and utilizes a TSSOP-48 package. It is classified under the AVC logic series and functions as a dual-supply bus transceiver for level translation applications.
This component is officially listed as obsolete by Texas Instruments and is no longer in active manufacturing. Procurement should focus on verifying the authenticity of existing stock or identifying approved substitute parts. Ensure that any available units are sourced from reputable distributors to avoid counterfeit products, as availability is limited to legacy inventory.
Engineers selecting this part must account for its obsolete status. Design-in decisions should prioritize replacement components that offer equivalent voltage translation capabilities and pin compatibility. Verify that alternative devices support the required memory card protocols and operate within the same electrical specifications to ensure seamless integration into existing systems.
The SN74AVCA406LZXYR belongs to the Advanced Very-low-voltage CMOS (AVC) family, which provides high-speed performance with low power consumption. This specific model is tailored for translating voltages in portable storage devices, facilitating communication between different voltage domains in mobile and embedded systems.
Nexperia USA Inc. 74LVCH8T245PW,118 is listed as a similar available substitute.
